Spot the teen: Lourdes Leon, 14, was out with her mother Madonna at the Vanity Fair Oscar party last night - and guess who was dressed the most outrageously...It's every 14-year-old's worst nightmare. You get a ticket to the coolest party in town, but then your mother spoils it by tagging along wearing inappropriate clothing and what's worse, exposes her behind to all and sundry.
According to Mail Online spies on the red carpet, that's just what happened when 52-year-old Madonna left daughter Lourdes blushing with embarrassment on the red carpet of the Vanity Fair party last night.
The Material Girl had gone out wearing little more than a black leotard and a few scraps of lace and the mortified teen was heard pleading: 'Mum, do you have to?!’ every time her popstar parent struck a pose and poked out her posterior for the waiting cameras.
Cheeky: Madonna was wearing a black leotard covered in see through black lace and a black fur waistcoat In an attempt to shame her mother into being less shameless, Lourdes was also heard to cry: 'But you tell me to behave like a grown-up' everytime her bottom got brandished again.
Still, when your mother has released a book called Sex, we guess that her going out without a skirt is the least of your worries.
Madonna was wearing the wacky outfit - finished off with fishnets and black platform stilettos - to the bash at the Sunset Tower Hotel in West Hollywood, Los Angeles.
All smiles: Raven-haired Lourdes appeared to have beaten her embarrassment as she grinned for the photographers
Pert: The popstar's posterior was still pretty peachy however - as displayed at the post-Oscars party The star was rumored to be have been hosting her own post-Oscars party, boasting a royal theme with music provided by British DJ Paul Oakenfold.
Lourdes meanwhile was wearing a tiny Aztec-inspired print mini-dress, thought to be from the fashion range she's launched with her mother, Material Girl.
Kelly Osbourne was recently announced as they label's new face, replacing Gossip Girl star Taylor Momsen.

Stepping out: Lourdes and her mother have also branched out together with their fashion label Material Girl And while the pair run the label together, we doubt that Lourdes will be wanting to borrow her mother's outfit anytime soon however.
In fact, the teen says it's the other way round.
She told Access Hollywood: '(My mom) does actually (borrow my clothes). I go into her closet - I'm not supposed to take things without asking, but she's always taking things without asking.
'I mean, she gets mad at me when I take things without asking her, but... she has such amazing like clothes, so it's like kind of annoying sometimes... She wears my shoes a lot and she wears my accessories.'
